Sound Diffuser Accessory with Wooden Sound Board and Rib Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speakers are limited in transmitting a wide range of frequencies and often produce sound in a specific, directive space, leading to interference and reduced sound quality, while also being bulky and costly.
Innovation Solution
A sound diffuser accessory utilizing a wooden sound board with varying thickness and rib structures to enhance sound transmission efficiency and quality, allowing for natural acoustic sound diffusion across a wide frequency range and in a 360-degree space, while being lightweight and aesthetically designed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional speakers are used to transmit sound, then sound can be produced in specific frequency ranges, but the frequency range is limited and sound transmission is directive rather than omnidirectional
Solution Approach 1:
The sound diffuser accessory segments the sound transmission function by using multiple sound boards (first sound board and second sound board) positioned at different orientations. Each sound board handles specific frequency ranges and transmission directions, collectively achieving omnidirectional sound diffusion across a wide frequency spectrum without requiring a complex multi-speaker system
Solution Approach 2:
The invention transitions from conventional planar speaker arrangements to a three-dimensional sound diffusion structure. The sound boards are positioned at different angles and heights, creating spatial distribution of sound sources that enables omnidirectional sound transmission in the vertical and horizontal dimensions simultaneously
2Adaptability or versatility
If multiple speakers with different characteristics are combined to cover wide frequency ranges, then frequency coverage improves, but overall dimensions and costs increase
Solution Approach 1:
Each sound board in the accessory is designed to perform multiple functions: it serves as both a structural support element and an acoustic radiation surface. The sound boards collectively handle multiple frequency ranges and transmission directions, making the entire accessory a universal sound diffusion system that replaces what would otherwise require multiple specialized speakers
Solution Approach 2:
The invention merges the functions of multiple speakers into a single integrated accessory structure. The first and second sound boards, along with their support structures, are combined into one unified unit that provides wide frequency coverage and omnidirectional transmission, eliminating the need for separate speaker systems
3Reliability
If speakers are mounted in closed or tuned boxes to prevent interference, then sound quality improves, but the structure becomes more complex and heavier
Solution Approach 1:
The invention extracts the sound diffusion function from the conventional enclosed speaker box structure. By using open sound boards mounted on support structures rather than enclosed boxes, the design eliminates unnecessary structural weight while maintaining sound quality through the natural resonance and radiation properties of the sound boards themselves
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
